After a couple of months using the preview build they just released the final version. (Only available for those that are on the preview already).
It's been a good experience so far with very few issues. Had to restart the upgrade to the final build once for instance. As a Chromebook owner I would say that Microsoft have done exactly the right things to keep my interest. Features like multiple desktops and the easy way you can pin windows to the left, right top, bottom, top left etc. etc. I find very productive.
Settings are also a lot easier than previous versions of windows. Really like the log-options. My favourite is the 4 digit pin. Still lots do discover like the photo's which I've not used at all.
Verdict: Upgrade as soon as you can.
